FIELD

The present disclosure relates to a self-cleaning method of a self-moving cleaning robot and a self-moving cleaning robot, and belongs to the field of manufacturing of small household appliances technology.

BACKGROUND

At present, the working mode of a water dust collector on the market is usually to spray water on the ground and collects sewage at the same time. However, after the work is finished, dirt such as dust will be accumulated in positions such as a dust suction port/washing port and an air duct of the machine, and it is very difficult for people to clean these positions by hand, and some positions cannot be even cleaned, which brings inconvenience to users. In addition, at the end of the work, remaining pollutants at the positions such as the dust suction port or the washing port may drop onto the working surface to cause secondary pollution.

The existing art No. CN106214079 discloses an automatic cleaning method and an apparatus. The description thereof discloses a working mode on page 4, in which an electric rotary mop cooperates with a front spraying head to spray water to the floor and a water suction port sucks away sewage. The last line on page 5 describes that a water inlet and a water drainage connection port are respectively connected to a water inlet and a water outlet of a user after the cleaning work is finished, and a cleaning machine automatically completes cleaning of the inside of the machine body. Obviously, a user needs to participate in the aforementioned cleaning mode to change an original working mode of the automatic cleaning equipment, so that the operation process is more cumbersome.

The existing art No. CN106214079 discloses a self-cleaning washing machine. The washing machine can clean part of sewage recycling components by itself. The description thereof on page 36 describes that the washing machine can directly clean an external water supply pipe by itself after finishing the work. Specifically, a cleaning brush needs to be separated from the external water supply pipe, and the external water supply pipe and a water outlet pipe head extends to a self-cleaning pipe together. Similarly, the aforementioned self-cleaning method also changes the original working mode of the cleaning mode, and is cumbersome in operation and unfavorable for long-time use.

SUMMARY

The present disclosure is directed to overcome the shortcomings in the existing art, and provides a self-cleaning method of a self-moving cleaning robot and a self-moving cleaning robot. Part of stains left at a rolling brush, a rolling brush cavity, a water suction port, a dust suction port and an air duct of the self-moving cleaning robot are automatically cleaned without changing an original working mode of the self-moving cleaning robot, and remaining pollutants can be prevented from dropping onto a working surface to cause secondary pollution. The self-moving cleaning robot is easy to operate and convenient to control, and a self-cleaning process of the self-moving cleaning robot can be effectively realized.

Solving the technical problem of the present disclosure is implemented by the following technical solution:

a self-cleaning method of a self-moving cleaning robot. The self-moving cleaning robot has both a working mode and a self-cleaning mode. When the self-moving cleaning robot needs to perform self-cleaning, the following steps are performed:

step 100: controlling the robot to enter the self-cleaning mode;

step 200: enabling the robot to initiate a self-cleaning action; and

step 300: after a self-cleaning condition is satisfied, ending the self-cleaning mode.

Specifically, the step 100 specifically includes: receiving, by the self-moving cleaning robot, an input signal of a user, and controlling the robot to enter the self-cleaning mode.

Or, the step 100 specifically includes: after the working mode of the self-moving cleaning robot is ended, automatically controlling the robot to enter the self-cleaning mode.

More specifically, the self-cleaning action in the step 200 is a self-cleaning action in a small region. The small region is 1 to 3 m².

In order to meet different cleaning requirements, the self-cleaning action in the small region includes in-situ operation action or in-situ spinning action or spiral walking action.

In order to achieve a better cleaning effect, the self-cleaning action in the step 200 specifically includes: increasing a suction force of the robot and/or increasing a water spray flow. Specifically, the suction force is increased to 1.5 times or above of the original force, and the water spray flow is increased to 1.5 times or above of the original flow.

In addition, the self-cleaning condition in the step 300 is a time condition, namely: self-cleaning time is preset in a control system of the robot. An automatic timing device arranged in the robot controls the self-cleaning time. At the preset time, the self-cleaning mode is ended.

The self-cleaning condition in the step 300 may also be a water level condition, namely: a water level lower limit threshold value is preset in the control system of the robot. After a water level detection device arranged in the robot detects that an actual water level reaches the threshold value, the self-cleaning mode is ended.

The present disclosure further provides a self-moving cleaning robot, including a machine body. A control system, a cleaning system and a walking system are arranged in the machine body. A self-cleaning mode switching control module is arranged in the control system. The self-cleaning mode switching control module initiates a self-cleaning mode according to an input signal of a user, or the self-cleaning mode switching control module controls the self-moving cleaning robot to enter the self-cleaning mode by itself to perform a self-cleaning action.

Specifically, the self-cleaning action is a self-cleaning action in a small region. The small region is 1 to 3 m².

More specifically, the self-cleaning action in the small region includes in-situ operation action or in-situ spinning action or spiral walking action.

In order to achieve a better cleaning effect, the self-cleaning action further includes: increasing a suction force in the cleaning system and/or increasing a water spray flow.

Based on the above, the present disclosure provides the self-cleaning method of a self-moving cleaning robot and the self-moving cleaning robot. Part of the stains left at the rolling brush, the rolling brush cavity, the water suction port, the dust suction port and the air duct of the self-moving cleaning robot are automatically cleaned without changing the original working mode of the self-moving cleaning robot, and remaining pollutants can be prevented from dropping onto the working surface to cause secondary pollution. The self-moving cleaning robot is easy to operate and convenient to control, and the self-cleaning process of the self-moving cleaning robot can be effectively realized.

DETAILED DESCRIPTION OF EXAMPLE EMBODIMENTS

FIG. 1 is a basic flow chart of a self-cleaning method of a cleaning machine of the present disclosure. As shown in FIG. 1, the present disclosure provides a self-cleaning method of a self-moving cleaning robot. The self-moving cleaning robot has both a working mode and a self-cleaning mode. When the self-moving cleaning robot needs to perform self-cleaning, the following steps are performed:

step 100: the robot is controlled to enter the self-cleaning mode;

step 200: the robot initiates a self-cleaning action; and

step 300: after a self-cleaning condition is satisfied, the self-cleaning mode is ended.

Specifically, the step 100 specifically includes that: the self-moving cleaning robot receives an input signal of a user, and controls the robot to enter the self-cleaning mode. In an actual operation process, the signal may be input by different modes according to different requirements of the user. For example, the user manually presses a self-cleaning mode button to control the robot to enter the self-cleaning mode, or the user may also remotely control the robot to enter the self-cleaning mode through a remote controller. Of course, the user may also control the robot to enter the self-cleaning mode through a mobile phone with an operation APP. Or, the step 100 may further specifically include that: the robot is controlled to enter the self-cleaning mode by itself. The various aforementioned operation processes may be all controlled to be performed at any time in a working state of the self-moving cleaning robot. For example, after the working mode of the self-moving cleaning robot is ended, or before the self-moving cleaning robot returns to a charging seat, the self-moving cleaning robot may be self-controlled to enter the self-cleaning mode. For another example, during working (such as lateral walking work, random walking work or spiral walking work), the self-moving cleaning robot may also enter the self-cleaning mode after receiving the signal of the user.

After the self-moving cleaning robot enters the self-cleaning mode, the self-cleaning action is initiated. Specifically, in order to improve the self-cleaning efficiency, the self-cleaning action in the step 200 is a self-cleaning action in a small region, and the small region is 1 to 3 m². In order to meet different cleaning requirements, the self-cleaning action in the small region includes in-situ operation action or in-situ spinning action or spiral walking action. In order to better complete the self-cleaning work and achieve the objective of washing cleaning components, such as a rolling brush and an air duct, the self-cleaning action in the step 200 specifically includes: increasing a suction force of the robot and/or increasing a water spray flow. Specifically, the suction force is increased to 1.5 times or above of the original force, and the water spray flow is increased to 1.5 times or above of the original flow.

That is, after the self-moving cleaning robot enters the self-cleaning mode, the motion mode thereof may be the in-situ operation action or the in-situ spinning action or the spiral walking action. Specifically, the in-situ operation action means that the self-moving cleaning robot is operated in situ with no motion, and only sucks water by a suction force, or only increases the suction force of the machine body and/or increase the water spray flow, and the machine body does not do any motion, either, and no motion track is formed. The in-situ spinning action means that the machine body of the self-moving cleaning robot moves clockwise or anticlockwise in the small region, and a motion track may be a whole circle or half of a circle. The spiral walking motion refers to a walking action done by the self-moving cleaning robot in the small region, forming a spiral motion track. The in-situ operation action or the in-situ spinning action or the spiral walking action may also be divided into an in-situ action or a moving action. Only one of the two actions generally occurs. The self-moving cleaning robot maintains the original working mode after entering the self-cleaning mode, and is caused to perform an action in the small region by adjusting a working state, or meanwhile, only the suction force or the water spray flow is increased. The operation mode is simple, and the self-cleaning efficiency is high.

In addition, the self-cleaning condition in the step 300 is a time condition, namely: self-cleaning time is preset in a control system of the robot. An automatic timing device arranged in the robot controls the self-cleaning time. At the preset time, the self-cleaning mode is ended. In a general case, the preset time is 10-20 seconds.

In addition to the time condition, the self-cleaning condition in the step 300 may also be a water level condition, namely: a water level lower limit threshold value is preset in the control system of the robot. After a water level detection device arranged in the robot detects that an actual water level reaches the threshold value, the self-cleaning mode is ended.

FIG. 2 is a schematic diagram of an outline structure of a self-moving cleaning robot of the present disclosure; and FIG. 3 is a sectional schematic diagram of a self-moving cleaning robot of the present disclosure. As shown in FIGS. 2 and 3, the present disclosure further provides a self-moving cleaning robot 1000, including a machine body. A control system, a cleaning system and a walking system (not shown in the figures) are arranged in the machine body. A self-cleaning mode switching control module is arranged in the control system. The self-cleaning mode switching control module initiates a self-cleaning mode according to an input signal of a user, or the self-cleaning mode switching control module controls the self-moving cleaning robot to enter the self-cleaning mode by itself. Specifically, in order to improve the self-cleaning efficiency, the self-moving cleaning robot performs a self-cleaning action after entering the self-cleaning mode, and the self-cleaning action is a self-cleaning action in a small region, and the small region is 1 to 3 m². In order to meet different cleaning requirements, the self-cleaning action in the small region includes in-situ operation action or in-situ spinning action or spiral walking action. In order to better complete the cleaning work, the self-cleaning action further includes: increasing a suction force in the cleaning system and/or increasing a water spray flow.

Embodiment 1

In combination with FIGS. 1 to 3, a working process in the present embodiment is as follows:

in a process that the self-moving cleaning robot 1000 cleans a floor, if a user finds that the cleaned floor has partial heavy stains, the user then manually presses a self-cleaning mode button on a remote controller to control the robot to enter the self-cleaning mode. At this time, the self-moving cleaning robot 1000 is switched from an original walking state into a state of spinning at the same place to perform cleaning within a small region of about 2.5 m². Meanwhile, the suction force of the self-moving cleaning robot 1000 is increased to 1.8 times of the original force, and the water spray flow is a double of the original flow. Since the water spray flow under the self-cleaning mode is increased, a water level lower limit threshold value is preset in the control system of the robot. After a water level detection device arranged in the robot detects that an actual water level reaches the threshold value, the self-cleaning mode is ended.

Embodiment 2

In combination with FIGS. 1 to 3, a working process in the present embodiment is as follows:

in a process that the self-moving cleaning robot 1000 cleans a floor, if a user finds that there is water on the partial floor, the user controls the robot to enter the self-cleaning mode through a mobile phone with an operation APP. After entering the self-cleaning mode, the self-moving cleaning robot 1000 moves within a small region of 2 m², and the suction force is increased to 3 times of the original force. Since the self-cleaning time is preset in the control system of the robot, an automatic timing device arranged in the robot controls the self-cleaning time, such as: 12 seconds. At the preset time, the self-cleaning mode is ended.

Embodiment 3

In combination with FIGS. 1 to 3, a working process in the present embodiment is as follows:

after the working mode of the self-moving cleaning robot 1000 is ended, the robot is controlled to enter the self-cleaning mode by itself. At this time, the self-moving cleaning robot 1000 moves within a small region of 3 m², forming a motion track, and the suction force and the water spray flow are both increased to a double of the original one. After the self-cleaning work is performed for 15 seconds, the self-cleaning mode is ended.

Embodiment 4

In combination with FIGS. 1 to 3, a working process in the present embodiment is as follows:

after the working mode of the self-moving cleaning robot 1000 is ended, the robot is controlled to enter the self-cleaning mode by itself. At this time, the self-moving cleaning robot 1000 is kept at a position where it enters the self-cleaning mode, and the suction force and the water spray flow are also kept unchanged. After the self-cleaning work is performed for 20 seconds, the self-cleaning mode is ended.

Based on the above, the present disclosure provides the self-cleaning method of a self-moving cleaning robot and the self-moving cleaning robot. Part of the stains, such as water spots, garbage and hairs, left at the rolling brush, the rolling brush cavity, the water suction port, the dust suction port and the air duct of the self-moving cleaning robot are automatically cleaned without changing the original working mode of the self-moving cleaning robot, and remaining pollutants can be prevented from dropping onto the working surface to cause secondary pollution. The self-moving cleaning robot is easy to operate and convenient to control, and the self-cleaning process of the self-moving cleaning robot can be effectively realized.
